Re: wd-wd45

If you are trying to tell them apart, the WD engine has a rectangle plate bolted on the right side of the block behind the mag/oil filter. The serial # on the rearend will be WD146607 or higher on a WD45. A curved shift lever is usually a WD45 but can be a late WD. Of course all the parts interchange so it could be a mixed breed too.

Everything that Aaron & Lonnie said is right on. Added info: The WD-45's manifold is much deeper. The spark plug slots in the head are much taller; The head is taller; the fenders are taller-higher mounts- to handle the 14.9 tires (the 45 rims are 14 in wide, the WDs are much smaller. 45s had a traction control guage below gas tank.
